FS8861 1.0A Adjustable and Fixed Voltage LDO
Linear Regulator
General Description
The FS8861 is a low-dropout linear regulator
that operates the input voltage from +2.5V to
+7.0V and delivers 1.0A load current.
The FS8861 is available in two types, either
fixed or adjustable output voltage. The output
voltage of the fixed types is preset at an
internally trimmed voltage 1.8V, 2.5V, or 3.3V.
The output range of the adjustable types is
from 1.25V to 5V.
The FS8861 consists of a 1.25V reference,
an error amplifier, and a P-channel pass
transistor allows the low 65µA (Typ.) ground
pin current. Other features include
short-circuit protection and thermal shutdown
protection.
Features
Low dropout voltage 700mV at 1.0A typ.
Adjustable output voltage (FS8861-CJ) or
fixed output voltage (FS8861-xxCJ) at 1.8V,
2.5V, or 3.3V
High output voltage accuracy
Fixed output voltage : 35mV
Adjustable output voltage : 50mV
Small output capacitor
Output current limit
Thermal overload shutdown protection
