■General Description
■Features
The XC6204 series are highly precise, low noise, positive voltage LDO
regulators manufactured using CMOS processes. The series achieves
high ripple rejection and low dropout and consists of a standard voltage
source, an error correction, current limiter and a phase compensation
circuit plus a driver transistor.
Maximum Output Current
Dropout Voltage
: 150mA
: 200mV (IOUT = 100mA)
Maximum Operating Voltage : 10V
Output Voltage Range
Highly Accurate
: 1.8V ~ 6.0V in 50mV increments
2%
:
Output voltage is selectable in 50mV increments within a range of 1.8V ~
6.0V.
Low Power Consumption
Standby Current
: TYP 70µA
: less than 0.1µA
: 70dB (10 kHz)
: 30µVrms
The series is also compatible with low ESR ceramic capacitors which
give added output stability. This stability can be maintained even during
load fluctuations due to the excellent transient response of the series.
The current limiter's foldback circuit also operates as a short protect for
the output current limiter and the output pin.
High Ripple Rejection
Low Output Noise
Operational Temperature Range
: -40°C ~ +85°C
Low ESR Capacitor Compatible
: Ceramic capacitor
The CE function enables the output to be turned off, resulting in greatly
reduced power consumption.
