Pin Functions
PINI/ODESCRIPTION
NO.NAME
A1INIInput voltage supply. For best transient response and to minimize input impedance, use the nominal value or larger capacitor from IN to ground. See the Recommended Operating Conditions table. Place the input capacitor as close to the IN and GND pins of the device as possible.
A2OUTORegulated output voltage. A low equivalent series resistance (ESR) capacitor is required from OUT to ground for stability. For best transient response, use the nominal recommended value or larger capacitor, as listed in the Recommended Operating Conditions table. Place the output capacitor as close to the OUT and GND pins of the device as possible. An internal 150Ω (typical) pulldown resistor prevents a charge from remaining on VOUT when the regulator is in shutdown mode (VEN < VEN(LOW)).
B1ENIEnable input. A low voltage (< VEN(LOW)) on this input turns the regulator off and discharges the output pin to GND. A high voltage (> VEN(HI)) on this pin enables the regulator output. This pin has an internal 500kΩ pulldown resistor to hold the regulator off by default. When VEN > VEN(HI), the 500kΩ pulldown is disconnected to reduce input current.
B2GND—Common ground.
