The response of other voltage options can compensation for the reference and cannot be omitted. be estimated by proper scaling. For light loads ≤1mA, a 1µF nonpolar output capacitor is usually adequate, but for higher loads (up to 75mA), the

output capacitor should be 2µF or greater. Figures 1 and The LT1461 family requires a capacitor on the input and 2 show the transient response to a 1mA load step with on the output for stability. The capacitor on the input is a 1µF output capacitor and a 50mA load step with a 2µF a supply bypass capacitor and if the bypass capacitors output capacitor. from other components are close (within 2 inches) they 0mA IOUT 1mA/DIV 1mA IOUT 50mA/DIV V V OUT OUT 200mV/DIV 20mV/DIV 1461 F01 1461 F02
