ST2L01
ST2L01 is DUAL VOLTAGE REGULATOR manufactured by STMicroelectronics.
DESCRIPTION
Both outputs are current limited and Specifically designed for data storage overtemperature protected. applications, this device integrates two voltage The very good thermal performances of the regulators, each one able to supply 1A. It is .. package SPAK with only 2°C/W of Thermal assembled in PPAK and in a new surface Resistance Junction to Case is important to mounting package named SPAK (Power Flex™) at underline. 5 pins. The first regulator block supply 3.3V to power the Read Channel and Memory Chips requiring this voltage. The second one is an Adjustable output voltage from 1.25V to 3.0V that
