High Speed LDO Regulators, Low ESR Cap. Compatible, ON/OFF Switch
■GENERAL DESCRIPTION
The XC6219/XC6211 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 XC6219/6211 series is ideal for today’s cutting edge mobile
phone.
Internally the XC6219/6211 includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase
compensators. The XC6219/6211’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 XC6219/6211 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.

■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 V
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
<Low ESR Capacitors>
With the XC6219/6211 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 (C
with a capacitance value of at least 1.0μF. Also, please connect an input capacitor (C
and the VSS pin in order to ensure a stable power input.
Stable phase compensation may not be ensured if the capacitor runs out capacitance when depending on bias and
temperature. In case the capacitor depends on the bias and temperature, please make sure the capacitor can ensure the
actual capacitance.
<Current Limiter, Short-Circuit Protection>
The XC6219/6211 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 XC6219/6211 series. In shutdown mode,
output at the V
selectable (please refer to the selection guide). Note that as the standard XC6219/6211B 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
OUT pin is controlled and stabilized by a system of negative feedback. The current limit circuit and short
L) is connected as close as possible to the output pin (VOUT) and the VSS pin. Please use an output capacitor
IN) of 1.0μF between the VIN pin
OUT pin will be pulled down to the VSS level via R1 & R2. The operational logic of the IC's CE pin is
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 V
IN and VSS wiring in particular.
3. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.
