Pin Functions

PIN TYPE DESCRIPTION
NAME USON DSGBA
BATT 1 C1 Input Bias input voltage; input range: 2.5 V to 5.5 V
EN 6 C3 Input Enable pin logic input: low = shutdown, high = active, normal operation. This pin should not be left floating. Tie to BATT if this function is not used.
GND 2 B2 Ground Ground
IN 3 A1 Input Power input voltage; input range: 0.7 V to 4.5 V, VIN ≤ VBATT
NC 5 — — Do not make connections to this pin.
OUT 4 A3 Output Regulated output voltage
