XC6238 Datasheet | Torex Semiconductor

DESCRIPTION The XC6238 series is a high speed LDO regulator that features high accuracy, low noise, high ripple rejection, low dropout and low power consumption. The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a phase pensation circuit. The CE function enables the circuit to be in stand-by mode by inputting low level signal. In the stand-by mode, the series enables the electric charge at the output capacitor CL to be discharged via the internal switch, and as a result the VOUT pin quickly returns to the VSS level. The output stabilization capacitor CL is also patible with low ESR ceramic capacitors. The output voltage is selectable in 0.05V increments within the range of 1.2V to 4.0V which fixed by laser trimming technologies. The over current protection circuit is built-in. This protection circuit will operate when the output current reaches current limit level. - APPLICATIONS - Mobile devices - Wireless munications - Modules - Mobile phones - FEATURES Maximum Output Current : 300m A Input Voltage Range : 1.6 ~ 5.5V Output Voltages : 2.0 ~ 4.0V(Accuracy ±1%) 1.2 ~ 1.95V(Accuracy ±20m V) 0.05V increments Dropout Voltage : 200m V＠IOUT=300m A (VOUT=3.0V) Low Power Consumption : 100μA Stand-by Current : 0.1μA High Ripple Rejection : 80d B＠f=1k Hz Protection Circuits : Current Limit (400m A) Short Circuit Protection Inrush Current Protection (Type H) Low ESR Capacitors : CIN=1μF, CL=1μF CE Function : Active High, CL High Speed Discharge Operating Ambient Temperature : -40℃ ~ 85℃ Small Package Environmentally Friendly : UFN-4A01 : EU Ro HS pliant, Pb Free Input Voltage: VCE [V] Rush Curren: IRUSH [m A] - TYPICAL APPLICATION CIRCUIT - TYPICAL PERFORMANCE CHARACTERISTICS XC6238H12 VIN = 2.2V, tr = 5μs, Ta = 25℃ VCE = 0→VIN, CIN = CL = 1.0μF...
