LDO Regulator Pos 3V 0.15A 5-Pin SC-70

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 SIP21106 regulator allows 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 is 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).
