DESCRIPTION
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.
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.
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-W 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-mA in the event
reversed battery is applied at the input, thus preventing
damage to the IC.
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_.
