I/O
D E S C R IP T IO N
Main power input pin. Connect this pin to a voltage source and an input
I capacitor. The HPL5331 sources current to VOUT pin by controlling the upper
NPN pass transistor, providing a current path from VIN pin.
Power and signal ground. Connect this pin to system ground plane with shortest
O
traces. The HPL5331 sinks current from VOUT pin by controlling the lower NPN
pass transistor, providing a current path to GND pin. This pin is also the ground
path for internal control circuitry.
Power input pin for internal control circuitry. ^VC^Co^Nn^Tn^Lect this pin to a voltage source,
I providing a bias for the internal control circuitry. A bypass capacitor is usually
connected near this pin.
Reference voltage input and active-low shutdown control pin. Apply a voltage to
this pin as a reference voltage for the HPL5331. Connect this pin to a resistor
I divider, between VIN and GND, and a capacitor for soft-start and filtering noise
purposes. Applying and holding this pin low by an open-drain tran^Cs^uis^rretⁿo^tr to shut
down the output.
Lim it
Output pin of the regulator. Connect this pin to load. Output capacitors
O
connected this pin improves stability and transient response. The output voltage
tracks the reference voltage and is capable of sourcing or sinking current up to
3A.
