PFKI SMD (TPS60400DBVR) Voltage Regulator IC.

TPS60400DBVR Unregulated 60-mA Charge Pump Voltage Inverter. The TPS6040x family of devices generates an unregulated negative output voltage from an input voltage ranging from 1.6 V to 5.5 V. The devices are typically supplied by a preregulated supply rail of 5 V or 3.3 V. Due to its wide input voltage range, two or three NiCd, NiMH, or alkaline battery cells, as well as one Li-Ion cell can also power them.

Features :

• Inverts Input Supply Voltage 
• Up to 60-mA Output Current 
• Only Three Small 1-µF Ceramic Capacitors Needed •
• Input Voltage Range From 1.6 V to 5.5 V 
• PowerSave-Mode for Improved Efficiency at LowOutput Currents (TPS60400)
• Device Quiescent Current Typical 65 µA
• Integrated Active Schottky-Diode for Start-up Into Load 
• Small 5-Pin SOT-23 Package 
• Evaluation Module Available TPS60400EVM-178

Applications :

•  LCD Bias • GaAs Bias for RF Power Amps
• Sensor Supply in Portable Instruments
• Bipolar Amplifier Supply
• Medical Instruments
• Battery-Operated Equipment

Pin Configuration and Functions :
