LOW DROP FIXED AND ADJUSTABLE POSITIVE VOLTAGE REGULATORS
DESCRIPTION
The UTC LD1117/A is a low dropout, 3-terminal positive
voltage regulator designed to provide output current up to
800mA/1A, There are adjustable version (VREF=1.25V) and
various fixed versions.
FEATURES
* Low dropout voltage
* Suitable for SCSI-2 active termination if VOUT set to 2.85V
* Output current up to 0.8A for 1117 and 1.0A for 1117A
* Built-in current limit and over temperature protection
* Available in ±1%(at 25°C) and 2% in all temperature range
* Low current consumption
5A ADJUSTABLE/FIXED LOW DROPOUT LINEAR REGULATORDESCRIPTIONThe UTC UZ1084-ADJ/Fixed voltages are low dropoutthree-terminal regulators with 5A output current capability. Thesedevices have been optimized for low voltage applications includingVTT bus termination, where transient response and minimum inputvoltage are critical.On-chip thermal limiting provides protection against anycombination of overload and ambient temperature that would createexcessive junction temperatures.FEATURES*Fast transient response*Low dropout Voltage at up to 5A*Load regulation : 0.5% typical*On-chip thermal limitingAPPLICATIONS*Desktop PCs, RISC and embedded processors’ supply*GTI, SSTL logic reference bus supply*Low voltage VCC logic supply*Battery-powered circuitry*Post regulator for switching supply*Cable and ADSL modems’ DSP core supply*Set Top Boxes and Web Boxes modules’ supply
HIGH CURRENT SWITCHIG APPLICATIONS FEATURES* Low collector-to-emitter saturation voltage* Good linearity of hFE* Small and slim package facilitating compactness of sets.* High fT* Fast switching speed
