3. Voltage Regulators _________________________________________________________________________________ XC6204 Series General Description (Can be used with low ESR Capacitor Compatible. ON – OFF Switch) High Speed LDO Regulators DETAILS Features Maximum Output Current: 150mA Dropout Voltage: 200mV @ 100mA Maximum Operating Voltage: 10V Output Voltage Range: 1.8V to 6.0V in 50mV steps Highly Accurate: ± 2% Low Power Consumption: TYP 100µA (XC6204A) TYP 75µA (XC6204B) Standby Current: less than 0. µA 1 High Ripple Rejection: 70dB (10 kHz) Low Output Noise: 30µVrms Operating Temperature Range: -40°C to +85°C Low ESR Capacitor Compatible: Ceramic Capacitor 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 amplifier, a current limiter, a phase compensation circuit and a driver tran sistor. Output voltage is selectable in 50mV increments within a range of 1.8V to 6.0V. 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. The CE function enables the output to be turned off, resulting in greatly reduced power consumption.
