n Detailed Description
drop-out regulator and microprocessor monitor. Unlike
bipolar regulators, the AME1300 supply current does not
increase with load current. In addition,V
and within regulation at very low load currents(an impor-
tant consideration in RTC and CMOS RAM battery back-
up applications) as well as with any type of capacitor (see
below). AME1300 pin functions are detailed below:

Ground Terminal.
Reference Bypass Input.
Connecting a 1000pF to this input further reduces output noise.
Shutdown Control Input. The regulator is fully enabled when a logic
high is applied to this input. The regulator enters shutdown when a
logic low is applied to this input. During shutdown, regulator output
voltage falls to zero, RESETB output remains valid and supply
current is reduced to 10 A (typ.)
No connect.
