General Description
The TC59 is a low dropout, negative output voltage
regulator designed specifically for battery-operated
systems. Its full CMOS construction eliminates the
wasted ground current typical of bipolar LDOs. This
reduced supply current significantly extends battery
life, particularly when the TC59 is operated in dropout.
Other TC59 key features include low supply current
(typically 3.0A) and low dropout operation (typically
120mV at 50mA). The TC59 is packaged in a small
3-Pin SOT-23A package.

2.0 PIN DESCRIPTIONS
The descriptions of the pins are listed in Table 2-1.
TABLE 2-1: PIN FUNCTION TABLE
3.0 DETAILED DESCRIPTION
The TC59 is a low quiescent current, precision fixed
negative output voltage LDO. Unlike bipolar linear
regulators, the TC59 supply current does not increase
proportionally with load current.
3.1 Output Capacitor
A minimum of 1F tantalum output capacitor is
required. The requirements for the output capacitor are
an equivalent series resistance (esr) greater than 0.1
and less than 5, with a self-resonant frequency
greater than 1MHz. To improve supply noise rejection
and transient response, larger output capacitors can be
used. Care should be taken when increasing COUT, that
the input impedance is not high enough to cause high
input impedance oscillation.
3.2 Input Capacitor
A 1F input capacitor is recommended for most
applications when the input impedance is on the order
of 10. When operating off of a battery input, or there
is a large distance from the input source to the LDO,
larger input capacitance may be required for stability.
When large values of output capacitance are used, the
input capacitance should be increased to prevent high
source impedance oscillations.

4.0 THERMAL CONSIDERATIONS
4.1 Power Dissipation
The amount of power dissipated internal to the low drop
out linear regulator is the sum of the power dissipation
within the linear pass device (P-Channel MOSFET),
and the quiescent current required to bias the internal
reference and error amplifier. The internal linear pass
device power dissipation is calculated multiplying the
voltage across the linear device times the current
through the device. The input and output voltages are
negative for the TC59. The power dissipation is
calculated using the absolute value of the voltage
difference between the input and output voltage.
TABLE 4-1: MAXIMUM POWER
DISSIPATION
EQUATION 4-1:
The internal power dissipation as a result of the bias
current for the LDO internal reference and error
amplifier is calculated by multiplying the ground or
quiescent current times the input voltage.
EQUATION 4-2:
The total internal power dissipation is the sum of
Equation 4-1 and Equation 4-2.
EQUATION 4-3:
For the TC59, the internal quiescent bias current is so
low (3A typical), the PD (Bias) term of the power
dissipation equation can be ignored. The maximum
power dissipation can be estimated by using the
maximum input voltage and the minimum output
voltage to obtain a maximum voltage differential
between input and output and multiplying the maximum
voltage differential by the maximum output current.
EQUATION 4-4:
For example, given the following conditions:
VIN = -7.0V ±5%
VOUT = -5.0V ±2%
IOUT = 1mA to 40mA
TAMBIENT (MAX)= 55°C
PMAX = (7V X (1.05) – (5.0V X 0.98)) X 40mA
PMAX = 98.0 milli-Watts
To determine the junction temperature of the device,
the thermal resistance from junction to air must be
known. The SOT-23-3 RJA is estimated to be
approximately 359°C/W when mounted on a 4-layer
board. The RJA will vary with physical layout, airflow
and other application specific conditions.
The device junction temperature is determined by
calculating the junction temperature rise above
ambient, then adding the rise to the ambient
temperature.

PD (Pass Device) = (VIN – VOUT) X IOUT

TJUNCTION = PD (MAX) X RJA + TAMBIENT

Note the following details of the code protection feature on Microchip devices:
Microchip products meet the specification contained in their particular Microchip Data Sheet.
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
Microchip is willing to work with the customer who is concerned about the integrity of their code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Microchip received ISO/TS-16949:2009 certification for its worldwide
headquarters, design and wafer fabrication facilities in Chandler and
Tempe, Arizona; Gresham, Oregon and design centers in California
and India. The Company’s quality system processes and procedures
are for its PIC® MCUs and dsPIC® DSCs, KEELOQ® code hopping
devices, Serial EEPROMs, microperipherals, nonvolatile memory and
analog products. In addition, Microchip’s quality system for the design
and manufacture of development systems is ISO 9001:2000 certified.
