General Description
The TC56 is a low supply current (11µA typical at
= 3V), low dropout CMOS linear regulator, with a
V
OUT
10V maximum input volt age range. CMOS cons truction
eliminates wasted ground current, typical of bipolar
regulators, for greater system efficiencies and longer
operating time in battery-powered systems. The TC56
enters shutdown mode when the shutdown control
input (SHDN
shut off, and supply current falls to 0.1µA maximum.
Normal operation is restored when SHDN
a logic high. Low current consumption, 10V supply
tolerance and space-saving 5-Pin SOT-23A packaging
makes the TC56 ideal for a wide varie ty of applicati ons.

3.0 DETAILED DESCRIPTION
The TC56 is a precision, fixed output LDO. Unlike
bipolar regulations, the TC56 supply current does not
increase with load current.
3.1 Output Capacitor
A 10µF tantalum capacitor from V
recommended. The output capacitor should have an
effective se ries re sistance greate r than 0.1Ω and less
than 5.0Ω, and a resonant frequency above 1M Hz. It is
recommended that a 4.7µF capacitor be connected
from V
to GND. When operating from sources other
IN
than batteries, supply noise rejection and transient
response can be improved by increasing the value of
the input and output c ap a ci tors and emplo yin g p a ss iv e
filterin g techniques.

3.2 Shutdown Input
The TC56 enters a low power shutdown mode when
the shutdown control input (SHDN

is reduced to 0.1µA (max). Normal operation is
restored when SHDN

4.0 THERMAL CONSIDERATIONS
4.1 Power Dissipation
The amount of power the regulator dissipates is
primarily a function of input and output voltage, and
output current. The following equation is used to
calculate worst case actual power dissipation.

PD ≈ (V
Where:
P
= Worst case actual power dissipation
D
= Maximum voltage on V

The maximum allowable power dissipation
(Equation 4-2) is a function of the maximum ambient

Equation 4-1 can be used in conjunction with

In this example, the TC56 dissipates a maximum of
64mW; below the allowab le limit o f 318mW. In a similar
manner , Equation4-1 and Equatio n 4-2 can be used to
calculate maximum current and/or input voltage limits.
4.2 Layout Considerations
The primary path of heat conductio n out of the p ackage
is via the package lea ds. Theref ore, layouts having a
ground plane, wide tra ces at the p ads , and wi de power
supply bus lines combine to lower θ
increase the maximum allowable power dissipation
limit.
