s General Description
The XC62FP series is a group of positive voltage output, three-pin
regulators, that provide a high current even when the input/output voltage
differential is small. Low power consumption and high accuracy is achieved
through CMOS and laser trimming technologies.
The XC62FP consists of a high-precision voltage reference, an error
correction circuit, and a current limited output driver. Transient response to
load variations have improved in comparison to the existing series.
SOT-23 (150mW) and SOT-89 (500mW) packages are available.
s Features
Max. output current: 250mA (within max. power dissipation, VOUT = 5.0V)
Output voltage: 2.0V to 6.0V in 0.1V increments (1.1V to 1.9V for custom
products)
Highly accurate: Output voltage ±2% (±1% for semi-custom products)
Low power consumption: Typ. 2.0µA at VOUT=5.0V
Output voltage temperature coefficient 0.1% /V: Typ. ±100ppm/:
Input stability: Typ. 0.2%/V
Small input/output differential: IOUT = 100mA at VOUT = 5.0V with a
0.12V differential.
Ultra small package: SOT-23 (150mW) mini-mold and SOT-89 (500mW)
mini-power mold
*TO-92 (300mW) package also available. (order basis)

s Notes on Use
1. Please use this IC within the stipulated absolute maximum ratings as the IC is liable to malfunction outside of such parameters.
2. There is a possibility that oscillation may occur as a result of the impedance present between the power supply and the IC's input. Where
impedance is 10or more, please use a capacitor (CIN) of at least 1µF.
With a large output current, operations can be stabilised by increasing capacitor size (CIN). If CIN is small and capacitor size (CL) is increased,
there is a possibility of oscillation due to input impedance.
In such cases, operations can be stabilised by either increasing the size of CIN or decreasing the size of CL.
3. Please ensure that output current (IOUT) is less than Pd ÷ (VIN -VOUT) and does not exceed the stipulated Continuous Total Power Dissipation
value (Pd) for the package.
4. Should you wish to increase output current (IOUT) and/or have the capability to exceed the stipulated Pd value, using a current boost circuit
(similar to the one shown below) is likely to lead to oscillation.
With such applications, we recommend use of a boost type voltage regulator, such as the Torex XC62EP series.
