微源现货 LP3994-33B3F 低压差线性稳压器

General description

The LP3994 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 LP3994 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 LP3994 is offered in SOT23-3，SOT23-5，SOT89-3 package.
