500mA Low-Dropout Linear Regulator in UCSP
General Description
The MAX1819 low-dropout linear regulator operates from
a 2.5V to 5.5V supply and delivers a guaranteed 500mA
load current with low 120mV dropout. The high-accuracy
(±1%) output voltage is preset at an internally trimmed
voltage (see the Selector Guide ) or can be adjusted from
1.25V to 5V with an external resistive-divider.
An internal PMOS pass transistor allows the low 125μA
supply current to remain independent of load, making
this device ideal for portable battery-operated equip-
ment such as personal digital assistants (PDAs), cellu-
lar phones, cordless phones, base stations, and
notebook computers.
Other features include an active-low, open-drain reset
output that indicates when the output is out of regula-
tion, a 0.1μA shutdown, short-circuit protection, and
thermal shutdown protection. The device is available in
a miniature 6-pin UCSP? package.
