DESCRIPTION

The SiP21106 BiCMOS 150 mA low noise LDO voltage reg-

ulators 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 cpacitor 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.

•

SiP21108 Adjustable Output Voltage

SiP21107 POK Error Flag

- 40 °C to + 125 °C Junction Temperature Range for

Operation

•

Uses Low ESR Ceramic Capacitors

• Fixed Voltage Output 1.3 V to 5 V in 50 mV Steps

The SiP21108 output is adjusted with an external resistor

network.

The SiP21106/7/8 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 tran-

sient response and regulation. In shutdown mode, the output

automatically discharges to ground through a 100 Ω NMOS.

The SiP21106/7/8 are available in TSOT23-5L and a super

thin lead (Pb)-free TSC75-6L packages for operation over

the industrial operation range (- 40 °C to 85 °C).
