150-mA Low Noise, Low Dropout Regulator
DESCRIPTION
The SiP21106 BiCMOS 150 mA low noise LDO voltage
regulators are the perfect choice for low battery operated low
powered applications. An ultra low ground current and low
dropout voltage of 135 mV at 150 mA load helps to extend
battery life for portable electronics. Systems requiring a quiet
voltage source, such as RF applications, will benefit from the
SiP21106 low output noise.
The SiP21107 do not require a noise bypass capacitor and
provides an error flag pin (POK or Power OK). POK output
requires an external pull-up resistor and goes low when the
supply has not come up to voltage.
The SiP21108 output is adjusted with an external resistor
network.
The SiP21106, SiP21107, SiP21108 regulators allow stable
operation with very small ceramic output capacitors,
reducing board space and component cost. They are
designed to maintain regulation while delivering 330 mA
peak current upon turn-on. During start-up, an active
pull-down circuit improves the output transient response and
regulation. In shutdown mode, the output automatically
discharges to ground through a 100
NMOS.
The SiP21106, SiP21107, SiP21108 are available in
TSOT23-5L a super thin lead (Pb)-free TSC75-6L and
SC70-5L packages for operation over the industrial operation
range (- 40 °C to 85 °C).

Function
By applying less than 0.4 V to this pin, the device will be turned off. Connect this pin to
V
IN
if unused. Do not leave floating.
Ground pin. For better thermal capability, directly connected to large ground plane.
Input supply pin. Bypass this pin with a 1 µF ceramic or tantalum capacitor to ground.
Output voltage. Connect C
OUT
between this pin and ground.
No Connection.
- BP (SiP21106): Noise bypass pin. For low noise applications, a 10 nF ceramic capacitor
should be connected from this pin to ground.
- Adj (SiP21108): Adjust input pin. Connect feedback resistors to program the output
voltage for trim value of 1.2005 V.
- POK (SiP21107): Power OK (error flag) pin. Open-drain output, which requires
connecting a pull-up resistor to V
IN
or V
OUT
. POK pin is actively high to indicate an output
normal operation condition on regulator and goes low to indicate under-voltage fault
