LP5952 350mA Dual Rail Linear Regulator
General Description
The LP5952 is a Dual Supply Rail Linear Regulator optimized for powering ultra-low
voltage circuits from a single Li-Ion cell or 3 cell NiMH/NiCd batteries.
In the typical post regulation application VBATT is directly connected to the battery (range 2.
5V.
.
.
5.
5V) and VIN is supplied by the output
voltage of the DC-DC Converter (range 0.
7V.
.
.
4.
5V).
The device offers superior dropout and transient features combined with very low quiescent currents.
In shutdown mode (Enable pin pulled low) the device turns off and reduces battery consumption to 0.
1µA (typ.
).
