Ultra LDO 1A Linear Regulator With
Pin Descriptions
VIN
– Power supply input pin. Bypass with a 2.2μF capacitor to GND
GND
– Ground.
VOUT
– Regulator Output pin. Sources up to 1A.
———
EN (5 Pin and 8 Pin) – Chip Enable (Active Low). This pin isn’t allowed to float.
EN (5 Pin and 8 Pin) – Chip Enable (Active High). This pin isn’t allowed to float.
BP (5 Pin and 8 Pin) – Bypass pin. It can connect to external 22nF capacitor to GND to reduce output
noise. The bypass pin could be floating if it’s unnecessary (Keep floating
cannot pull low and pull high).
ADJ (5 Pin and 8 Pin) –The output voltage can either be set by the internal feedback resistors when
this pin is grounded, or be set by the external feedback resistors when using
a resistive divider.
