ꢀGENERAL DESCRIPTION
ꢀFEATURES
The XC6219 series are highly accurate, low noise, CMOS LDO
Voltage Regulators. Offering low output noise, high ripple rejection
ratio, low dropout and very fast turn-on times, the XC6219 series
is ideal for today’s cutting edge mobile phone.

+30mV (VOUT<1.5V)
25µA (TYP.)
Dropout Voltage
Internally the XC6219 includes a reference voltage source, error
amplifiers, driver transistors, current limiters and phase
compensators. The XC6219’s current limiters' foldback circuit
also operates as a short protect for the output current limiter and.
the output pin. The output voltage is set by laser trimming.
Voltages are selectable in 50mV steps within a range of
0.9V to 5.0V. The XC6219 series is also fully compatible with low
ESR ceramic capacitors, reducing cost and improving output stability.

This high level of output stability is maintained even during frequent
load fluctuations, due to the excellent transient response performance
and high PSRR achieved across a broad range of frequencies.
The CE function allows the output of regulator to be turned off,
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.

ꢀOPERATIONAL EXPLANATION
<Output Voltage Control>
The voltage divided by resistors R1 & R2 is compared with the internal reference voltage by the error amplifier. The P-channel MOSFET, which is connected
to the VOUT pin, is then driven by the subsequent output signal. The output voltage at the VOUT pin is controlled and stabilized by a system of negative
feedback. The current limit circuit and short protect circuit operate in relation to the level of output current. Further, the IC's internal circuitry can be shutdown
via the CE pin's signal.

Reference
<Low ESR Capacitors>
With the XC6219 series, a stable output voltage is achievable even if used with low ESR capacitors as a phase compensation circuit is built-in. In order to
ensure the effectiveness of the phase compensation, we suggest that an output capacitor (CL) is connected as close as possible to the output pin (VOUT)
and the VSS pin. Please use an output capacitor with a capacitance value of at least 1µF. Also, please connect an input capacitor (CIN) of 0.1µF between the
VIN pin and the VSS pin in order to ensure a stable power input.
<Current Limiter, Short-Circuit Protection>
The XC6219 series includes a combination of a fixed current limiter circuit & a foldback circuit, which aid the operations of the current limiter and circuit
protection. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. As a result of this drop in
output voltage, the foldback circuit operates, output voltage drops further and output current decreases. When the output pin is shorted, a current of about
50mA flows.
<CE Pin>
The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6219 series. In shutdown mode, output at the VOUT pin will be pulled
down to the VSS level via R1 & R2. The operational logic of the IC's CE pin is selectable (please refer to the selection guide on page 2). Note that as the
standard XC6219B type's regulator 1 and 2 are both ' High Active/No Pull Down', operations will become unstable with the CE pin open. Although the CE pin is
equal to an inverter input with CMOS hysteresis, with either the pull-up or pull-down options, the CE pin input current will increase when the IC is in operation.
We suggest that you use this IC with either a VIN voltage or a VSS voltage input at the CE pin. If this IC is used with the correct specifications for the CE pin,
the operational logic is fixed and the IC will operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry.
ꢀNOTES ON USE
1. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be exceeded.
2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current. Please keep the resistance
low between VIN and VSS wiring in particular.
3. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
