SiP21102  
Vishay Siliconix  
150-mA Low-Noise LDO Regulator  
With Error Flag and Discharge  
FEATURES  
DESCRIPTION  
•
•
Ultra low dropout - 130 mV at 150 mA load  
Low noise - 75 µVRMS (10 Hz to 100 kHz  
bandwidth)  
Out-of-regulation error flag (power good)  
Shutdown control  
110 µA ground current at 150 mA load  
1.5 % guaranteed output voltage accuracy  
300 mA peak output current capability  
Uses low ESR ceramic capacitors  
Fast start-up (50 µs)  
Fast line and load transient response (≤ 30 µs)  
1 µA maximum shutdown current  
Output current limit  
The SiP21102 is a 150 mA CMOS LDO (low dropout) voltage  
regulator. It is the perfect choice for low voltage, low power  
applications. An ultra low ground current makes this part  
attractive for battery operated power systems. The SiP21102  
also offers ultra low dropout voltage to prolong battery life in  
portable electronics. Systems requiring a quiet voltage  
source, will benefit from the SiP21102’s low output noise.  
The SiP21102 is designed to maintain regulation while  
delivering 300 mA peak current, making it ideal for systems  
that have a high surge current upon turn-on.

For better transient response and regulation, an active pull-  
down circuit is built into the SiP21102 to clamp the output  
voltage when it rises beyond normal regulation. The  
SiP21102 automatically discharges the output voltage by  
connecting the output to ground through a 100 Ω n-channel  
MOSFET when the device is put in shutdown mode.  
Reverse battery protection  
Built-in short circuit and thermal protection  
Output, auto-discharge In shutdown mode  
Fixed 1.2 V, 1.8 V, 2.5 V, 2.6 V, 2.8 V, 2.85 V, 3.0 V,  
3.3 V, 5.0 V output voltage options  
SC70-5 package  
The SiP21102 features reverse battery protection to limit  
reverse current flow to approximately 1 µA in the event  
reversed battery is applied at the input, thus preventing  
damage to the IC.  
•
•
Compliant to RoHS Directive 2002/95/EC  
The SiP21102 is available in a lead (Pb)-free 5-pin SC70  
package for operation over the industrial operating range  
(- 40 °C to 85 °C).  
APPLICATIONS  
•
Cellular phones, wireless handsets
