Ultra low dropout - 250 mV at 250 mA load  
Ultra low noise - 30 µVRMS (10 Hz to 100 kHz)  
Shutdown control  
The SiP21103 is a 250 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  
SiP21103 also offers ultra low dropout voltage to prolong  
battery life in portable electronics. Systems requiring a quiet  
voltage source, such as RF applications, will benefit from the  
SiP21103’s ultra low output noise. An external noise bypass  
capacitor connected to the device’s BP pin can further  
reduce the noise level. The SiP21103 is designed to  
maintain regulation while delivering 400 mA peak current,  
making it ideal for systems that have a high surge current  
upon turn-on.  
130 µA ground current at 250 mA load  
2 % guaranteed output voltage accuracy  
400 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  
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  
MLP22-5 PowerPAK® package  
Compliant to RoHS directive 2002/95/EC  
For better transient response and regulation, an active pull-  
down circuit is built into the SiP21103 to clamp the output  
voltage when it rises beyond normal regulation. The  
SiP21103 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.  
•
•
The SiP21103 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.  
APPLICATIONS  
•
Cellular phones, wireless handsets  
•
Noise-sensitive electronic systems, laptop and palmtop  
computers  
The SiP21103 is available in a lead (Pb)-free 5-pin MLP22  
PowerPAK package and is specified to operate over the  
industrial temperature range of - 40 °C to 85 °C.
