" General Description

" Features

The XC6204 series are highly precise, low noise, positive voltage LDO regulators

manufactured using CMOS processes. The series achieves high ripple rejection

and low dropout and consists of a standard voltage source, an error correction,

current limiter and a phase compensation circuit plus a driver transistor.

Output voltage is selectable in 50mV increments within a range of 1.8V ~ 6.0V.

The series is also compatible with low ESR ceramic capacitors which give added

output stability. This stability can be maintained even during load fluctuations due

to the excellent transient response of the series.

Maximum Output Current : 150mA

Dropout Voltage : 200mV (IOUT = 100mA)

Maximum Operating Voltage : 10V

Output Voltage Range : 1.8V ~ 6.0V in 50mV increments

Highly Accurate : 2ꢀ

Low Power Consumption : TYP 75µA

Standby Current : less than 0.1µA

High Ripple Rejection : 70dB (10 kHz)

Low Output Noise : 30µVrms

The current limiter's foldback circuit also operates as a short protect for the output

current limiter and the output pin.

Operating Temperature Range : -40^OC ~ +85^OC

The CE function enables the output to be turned off, resulting in greatly reduced

power consumption.

" Operational Explanation

Output voltage control with the XC6204 series :

VIN

ON/OFF

Control

each circuit

CE

The voltage divided by resistors R1 & R2 is compared with

the internal reference voltage by the error amplifier.

Current

Limit

The P-Channel MOSFET, which is connected to the VOUT

pin, is then driven by the subsequent output signal. The

ouput voltage at the VOUT pin is controlled & stabilised by

a system of negative feedback.

VOUT

VSS

R2

R1

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.

Voltage

Reference

Low ESR Capacitors

With the XC6204 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 XC6204 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 (refer to the data on page 5). When the output pin is shorted, a current of about 60mA flows.

CE Pin

The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6204 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 XC6204B type is ' 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 IC will operatenormally. However, supply current may increase as a result of through current in

the IC's internal circuitry if a voltage between 0.25V and 1.5V is input.

" 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 impedence is high, operations may become unstable due to noise and/or phase lag depending on output current.

Please strengthen 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.
