LP2951-33D

The LP2951-33D is a bipolar low-dropout (LDO) Linear Regulator that can accommodate a wide input supply-voltage range of up to 30V. By tying the OUTPUT and SENSE pins together and the FEEDBACK and VTAP pins together the device output is fixed output to 3.3V. The device also offers additional functionality that makes it particularly suitable for battery-powered applications. For example, a logic-compatible shutdown feature allows the regulator to be put in standby mode for power savings. In addition, there is a built-in supervisor reset function in which the ERROR\ output goes low when VOUT drops by 6% of its nominal value for whatever reasons - due to a drop in VIN, current limiting or thermal shutdown.
