APPLICATION CIRCUITS

In Fig.7 the quiescent current equals Iq +IRdivider.

The specified quiescent current equals Iq. When the

supply voltage is connected, the regulator will switch on

when the supply voltage exceeds 7.6 V. With the aid of a

timing capacitor at pin 6 the reset can be delayed (the

timer starts at the same moment as the regulator is

switched on).

Forced reset can be accomplished by short-circuiting the

timer capacitor by using the push button switch. When the

push button is released again, the timer restarts (only

when the regulator is on) causing a second reset on both

RES1 and RES2.

The maximum output current of the regulator equals:

When Tamb =85 °C, the maximum output current equals

138 mA. At lower ambient (Tamb < 0) temperature the

maximum output current equals 320 mA.
