80mA Low Noise LDO Voltage Regulator
with Enable Function
GENERAL DESCRIPTION
TS5213 is an efficient linear voltage regulator with ultra-
low noise output, very low dropout voltage (typically
50mV at light loads and 320mV at 80mA), and very low
ground current (225μA at 20mA), providing high output
current even when the application requires very low
dropout voltage. The Chip Enable (EN) includes a
CMOS or TTL compatible input allows the output to be
turned off to prolong battery life. When shutdown,
power consumption drops nearly to zero. TS5213 is
included a precision voltage reference, error correction
circuit, a current limited output driver, over temperature
shutdown and revered battery protection.

Note:
1. Exceeding the absolute maximum rating may damage the device.
2. The maximum allowable power dissipation at any T
A
is P
D(MAX)
= [T
J(MAX)
- Ta] + R
θJA
. Exceeding the maximum allowable
power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
3. Devices are ESD sensitive. Handling precautions recommended.
4. The device is not guaranteed to function outside its operating rating.
5. Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
6. Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load
regulation in the load range from 1mA to 80mA. Changes in output voltage due to heating effects are covered by the
thermal regulation specification.
7. Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value
measured at 1V differential.
8. Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the
supply is the sum of the load current plus the ground pin current.
9. Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation is applied,
excluding load or line regulation effects. Specifications are for a 80mA load pulse at V
IH
=16V for t=10ms.
