150mA Low Noise LDO Voltage Regulator
with Enable Function
GENERAL DESCRIPTION
TS5205 is an efficient linear voltage regulator with ultra-
low noise output, very low dropout voltage (typically
17mV at light loads and 165mV at 150mA), and very low
power consumption (600µA at 100mA), 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. TS5205 is included a
precision voltage reference, error correction circuit, a
current limited output driver, over temperature
shutdown, revered battery protection and a reference
bypass pin to improve its already excellent low-noise
performance.

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

. Exceeding the maximum allowable
power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
3. The device is not guaranteed to function outside its operating rating.
4. Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
5. 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 150mA (5V version) and 1mA to 120mA (V
OUT
<5V version). Changes in output
voltage due to heating effects are covered by the thermal regulation specification.
6. 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.
7. 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.
8. 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 150mA load pulse at V
IN
=16V for t=10ms.
