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).
