MICROCHIP TC59

TC59
Low Dropout, Negative Output Voltage Regulator
Features
General Description
• Low Dropout Voltage
- Typically 120mV @ 50mA; 380mV @ 100mA
for -5.0V Output Part
• Tight Output Voltage Tolerance: ±2% Max
• Low Supply Current: 3.5µA, Typ
• Small Package: 3-Pin SOT-23A
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.
Applications
•
•
•
•
Cellular Phones
Battery Operated Systems
Palmtops
Portable Cameras
Other TC59 key features include low supply current
(typically 3.0µA) and low dropout operation (typically
120mV at 50mA). The TC59 is packaged in a small
3-Pin SOT-23A package.

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 1µF tantalum output capacitor is
required. The requirements for the output capacitor are
an equivalent series resistance (esr) greater than 0.1Ω
and less than 5Ω, 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.
 2002 Microchip Technology Inc.
3.2
Input Capacitor
A 1µF input capacitor is recommended for most
applications when the input impedance is on the order
of 10Ω. 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.

THERMAL CONSIDERATIONS
4.1
Power Dissipation
EQUATION 4-3:
PTOTAL = PD (Pass Device) + PD (Bias)
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.
For the TC59, the internal quiescent bias current is so
low (3µA 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:
PMAX = (V IN (MAX) – VOUT (MIN)) X IOUT (MAX)

For example, given the following conditions:
VIN
= -7.0V ±5%
VOUT
= -5.0V ±2%
IOUT
= 1mA to 40mA
TAMBIENT (MAX) = 55°C
EQUATION 4-1:
PD (Pass Device) = (VIN – V OUT) X IOUT
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:
PD (Bias) = VIN X IGND
The total internal power dissipation is the sum of
Equation 4-1 and Equation 4-2.
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 RθJA is estimated to be
approximately 359°C/W when mounted on a 4-layer
board. The RθJA 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.
EQUATION 4-5:

TEMPERATURE
(SOT-23 EXAMPLE)
TJUNCTION = PD (MAX) X RθJA + TAMBIENT
TJUNCTION = 98.0 milli-Watts X 359°C/W + 55°C
TJUNCTION = 90.2°C
