TECHNICAL NOTES

Phase Compensation

In LDO (Low Drop Out) regulators, phase compensation is provided to secure stable operation even when

1.0μF or more and proper ESR

(Equivalent Series Resistance).

Depending on the capacitor size, manufacturer, and part number, the bias characteristics and temperature

characteristics are different. Evaluate the circuit taking actual characteristics into account. Especially for the

1.75-V-output product, it is recommended to use 2.2µF or higher output capacitor when the product is used

under the low-

temperature environment such as −20°C or lower.

If you use a tantalum type capacitor and the ESR value of the capacitor is large, the output might be

unstable. Evaluate your circuit including consideration of frequency characteristics.
