The series features high accuracy, low output noise, high ripple rejection and low dropout and consists of a voltage reference, error amplifier, driver transistor, current limiter, thermal shutdown circuit and phase compensation circuit. Each output voltage is set independently by laser trimming and selectable in 0.05V increments within a range of 0.8 to 5.0V. The EN function turns each output of the two regulators off independently. In this state, the electric charge at the output capacitor (CL) is discharged via the internal auto-discharge switch, and as a result the VOUT voltage quickly returns to the VSS level. The output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors. The high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance. VR1 and VR2 are completely isolated so that a cross talk during load fluctuations is minimized. ■APPLICATIONS ● Mobile phones ● Cordless phones, Wireless communication equipment ● Portable games ● Digital still cameras, Digital video cameras ● Portable audio equipment ● PDAs ■ FEATURES Input Voltage Range : 1.5~6.0V Maximum Output Current : ch1.300mA / ch2.100mA Output Voltage Range : 0.8~5.0V Output Accuracy : ±1% (XC6419A/B) ±20mA@ VOUT≦2.0V ±2% (XC6419C/D) ±30mA@ VOUT≦1.5V Dropout Voltage ( VOUT=2.8V) : ch1.115mV@IOUT=200mA ch2.115mV@IOUT=50mA Low Power Consumption : ch1.28μA / ch2.23μA Stand-by Current : Less than 0.1μA Ripple Rejection : 60dB@f=1kHz Current Limit : ch1.400mA / ch2.150mA Low ESR Capacitor CL High Speed Discharge Small Packages : USP-6C, SOT-26 ■TYPICAL APPLICATION CIRCUITS ETR0338-003 ■TYPICAL PERFORMANCE CHARACTERISTICS ●Dropout Voltage vs. Output Current VOUT=2.8V ch2 Maximum Output Current ch1 Maximum Output Current Output Current : IOUT (mA) ch2 ch1 |
