150毫安CMOS LDO稳压器，快速启动，启用 150 mA CMOS LDO Regulator with Fast Start, Enable
Description
The FAN2534/FAN2535 family of micropower low-dropout voltage regulators utilize CMOS technology to offer a new level of cost-effective performance in GSM, TDMA, and CDMA cellular handsets, laptop and notebook computers, and other portable devices. Proprietary design technics ensure high ripple rejection. Other features include low noise, short circuit current limit, thermal shutdown circuit, low dropout voltage, fast enable required in CDMA handset applications, exceptional loop stability to accommodate a wide variety of external capacitors, and a compact SOT23-5 surface-mount package. These products offer significant improvements over older Bipolar and CMOS designs and are pin-compatible with many popular devices.
