CapFREE™ 150 mA, low-noise, low-dropout regulator
with thermal protection
SA57017-XX
GENERAL DESCRIPTION
The CapFREE™ SA57017 is one of a family of unique low dropout
regulators. It needs no external capacitors, offers a low output noise
voltage of 25
µVrms,
and an ultra-low dropout voltage of 50 mV
max. @ 50 mA output current. Reverse battery current is extremely
low, 0.5
µA
typical.
To accommodate high density layouts, it is packaged in the small
footprint 5 leaded SOT23-5 (SO5) and a 5-bump Chip-Scale
package (WL-CSP5). It is ideal for all portable and cellular phone
applications.
Additional features include power and thermal shutdown, output
current limitation, power OK status via the PWROK pin, thermal
warning, and external logic-controlled on-off via the PWRON pin,
and reverse battery protection.
