L4948规格书详情
DESCRIPTION
The L4946B is a quad output low drop voltage regulator. The four outputs are a low drop 10V at 125mA (VO1), a 8.5V at 250mA (VO2), a 5V at 200mA (VO3) and a low drop 5V st-by line at 100mA (VO4).
The IC includes a monitoring circuit to warn if a low voltage or no voltage condition is occurring. VO1,2,3 are off during st-by mode.
The STCAP pin allows the battery voltage to decay slowly giving the µP time to store data. This IC is designed for supplying microcomputer controlled systems specially in automotive applications.
■ 4 OUTPUTS: 10V (125mA); 8.5V (250mA); 5V (200mA); 5V (100mA)
■ 10V AND 5V (100mA) OUTPUT ARE LOW DROP
■ 5V (100mA) ST-BY OUTPUT VOLTAGE
■ EARLY WARNING OUTPUT FOR SUPPLY UNDERVOLTAGE (LVW)
■ THERMAL SHUTDOWN AND CURRENT LIMITATION (FOLDBACK)
■ REVERSE BATTERY AND LOAD DUMP PROTECTION
■ INHIBIT (ON/OFF) AND RESET FUNCTIONS
