Ultra LDO 2A Linear Regulator With Adjustable & Bypass Pin
Pin Descriptions
VIN
– Power supply input pin. Bypass with a 4.7μF capacitor to GND
GND
– Ground.
VOUT
– Regulator Output pin. Sources up to 2A.
———
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.
PGOOD (8 Pin)
– Power Good open Drain output.
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.
