Bypass (BYP)

The capacitor connected from BYP to OUT filters the

noise of the reference, feedback resistors, and regula-

tor input stage and provides a high-speed feedback

path for improved transient response. A 0.01µF capaci-

tor rolls off input noise at approximately 32Hz.

The slew rate of the output voltage during startup is

also determined by the BYP capacitor. A 0.01µF

capacitor sets the slew rate to 5V / ms. This startup rate

results in a 50mA slew current drawn from the input at

startup to charge the 10µF output capacitance.
