LPSemi/微源半导体 LP3994B SOT89-3 宽输入范围高性能LDO
General description
The LP3994B is a high-performance low dropout(LDO)voltage regulator with wide input voltage range and low quiescent current (1.5 μ A typical). The device is suitable for a multitude of applications which require a regulated supply of up to 150mA load current. The device uses an advanced CMOS process and a PMOSFET to achieve fast start-up, high output voltage accuracy and excellent transient response performance.
The LP3994B comes in standard fixed output voltage3.3V and 5.0V. The device is stable with a 1.0μF~10μF ceramic output capacitor, The device is protected from short circuit by the current limit function and from over-heating by thermal overload protection.
The LP3994B is offered in SOT23-3,SOT23-5,SOT89-3 package.
