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 VININ 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.).
The LP5952 also features internal protection against over-temperature, over-current, and under-voltage conditions. Performance is specified for a -40°C to +125°C junction temperature range.
The LP5952 is available in a micro SMD package, lead free. The device is available in fixed output voltages in the range of 0.5V to 2.0V.
The evaluation board is designed to enable independent evaluation of the LP5952 electrical performance. Each board is pre-assembled and tested in the factors.
The evaluation kits are available in four options: LP5952TL-1.2EV, LP5952TL-1.3EV, LP5952TL-1.5EV, and LP5952TL-1.8EV. The board contains the LP5952 and input and output capacitors connected to GND.
