Low-Dropout, Low I Q , 1A Linear Regulator
TEMP PIN- V OUT ?
General Description
The MAX1793 low-dropout linear regulator (LDO) oper-
ates from +2.5V to +5.5V and delivers a guaranteed 1A
load current with a low 210mV dropout. The high-accu-
racy (±1%) output voltage is preset at an internally
trimmed voltage (see the Ordering Information) or can
be adjusted from 1.25V to 5.0V with an external resis-
tor-divider.
An internal pMOS pass transistor allows a low 125μA
supply current, making the MAX1793 ideal for battery-
operated portable equipment. Other features include a
built-in reset output, low-power shutdown, and short-cir-
cuit and thermal-overload protection. The MAX1793 is
available in a 1.5W, 16-pin power TSSOP package,
which is 30% smaller than a SOT223 package and only
1.1mm high.
