• Manufacturer Part Number: sa57000-30d
• Description: Capfree? 150 Ma, Low-noise, Low Dropout Regulator With Thermal Protection
• Manufacturer: NXP Semiconductors

Philips Semiconductors
GENERAL DESCRIPTION
The CapFREE
dropout regulators. It needs no external capacitors, offers a low
output noise voltage of 30 V
of 55 mV @ 50 mA output current. To accommodate high density
layouts, it is packaged in the small footprint 5 leaded SOT23-5 (SO5)
and a 5-bump Wafer Level 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, thermal warning, and external
logic-controlled on-off via the PWRON pin.
