GENERAL DESCRIPTION FEATURES
The XC6219 series are highly accurate, low noise, CMOS LDO Maximum Output Current 150mA (VOUT<1.75V)
Voltage Regulators. Offering low output noise, high ripple rejection 240mA (VOUT>
ratio, low dropout and very fast turn-on times, the XC6219 series (300mA limit (TYP))
is ideal for today’s cutting edge mobile phone. Dropout Voltage 200mV (IOUT=100mA)
Internally the XC6219 includes a reference voltage source, error Operating Voltage Range 2.0V ~ 6.0V
amplifiers, driver transistors, current limiters and phase Output Voltage Range 0.9V ~ 5.0V (50mV steps)
compensators. The XC6219’s current limiters' foldback circuit Highly Accurate +
also operates as a short protect for the output current limiter and. +
the output pin. The output voltage is set by laser trimming. Low Power Consumption 25µA (TYP.)
Voltages are selectable in 50mV steps within a range of Standby Current Less than 0.1µA (TYP.)
0.9V to 5.0V. The XC6219 series is also fully compatible with low High Ripple Rejection 65dB (10kHz)
ESR ceramic capacitors, reducing cost and improving output stability. Operating Temperature Range - 40
This high level of output stability is maintained even during frequent Low ESR Ceramic Compatible Ceramic Capacitor load fluctuations, due to the excellent transient response performance Ultra Small Packages SOT-25 (SOT-23-5) and high PSRR achieved across a broad range of frequencies. SOT-89 The CE function allows the output of regulator to be turned off, USP-6B resulting in greatly reduced power consumption. The XC6219 series is available in the SOT-25 (SOT-23-5), SOT-89 or USP-6B ‘chip-scale’ package. Measuring only 2.0mm x 1.8mm the USP-6B is perfect for applications where PCB area is critical.

Selection Guide
The following options for the CE pin logic and internal pull-up/down are available:
High Active + no pull-down resistor built-in (standard) High Active + 2.0MΩ pull-down resistor built-in <between CE-VSS> (semi-custom) Low Active + no pull-up resistor built-in (semi-custom) Low Active + 2.0MΩ pull-up resistor built-in <between VIN-CE> (semi-custom)
Note: *With the pull-up resistor or pull-down resistor built-in types, the supply current during operation will increase by VIN / 2.0MΩ (TYP.)
