Power.P.N
primary-cell battery boost regulator
The Power.P.N tile is a primary-cell power-management subsystem based on the Nordic nPM2100 PMIC. Drawing power from one or two alkaline cells or a single coin cell battery with a total voltage of between 0.7 and 3.4V, the boost regulator delivers 1.8 V to 3.3 V at up to 150 mA, with a secondary LDO/load-switch output providing 0.8 V to 3.0 V at up to 50 mA. In addition to I2C configuration, monitoring, and advanced fuel gauging, pads are exposed for power-good indication, reset, ship-mode control, and one GPIO.

Application Notes
VOUT
The output voltage of the 150mA-max boost regulator defaults to 1.8V or the battery voltage (VBATT+), whichever is GREATER, with higher voltages up to 3.3V configurable via I2C.
VLDO
Off by default, the 50mA regulated output can be configured via I2C to be between 0.8 and 3.0V.
PG / RESET
The electrical configuration of pad 2 allows it to be function simultaneously as both the power-good output (as an open-drain with a pull-up resistor) and an active-low reset input.
