LT3012EDE#PBF

LT3012 is a high voltage, micropower low dropout linear regulator. This device is capable of supplying 250mA of output current with a dropout voltage of 400mV. Designed for use in battery-powered or high voltage systems, the low quiescent current (40µA operating and 1µA in shutdown) makes the device an ideal choice. Quiescent current is also well controlled in dropout. Other features of the device include the ability to operate with very small output capacitors. The regulator is stable with only 3.3µF on the output while most older devices require between 10µF and 100µF for stability. Small ceramic capacitors can be used without any need for series resistance (ESR) as is common with other regulators. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting and reverse current protection. It is used in applications like low current high voltage regulators, regulator for battery-powered systems, telecom applications, automotive applications.

• Wide input voltage range from 4V to 80V
• Low quiescent current is 40µA typical
• No protection diodes needed, adjustable output from 1.24V to 60V
• Quiescent current in shutdown is 1µA typical at (VIN = 6V, VSHDN = 0V)
• Stable with 3.3µF output capacitor, stable with aluminum, tantalum or ceramic capacitors
• Reverse-battery protection, no reverse current flow from output to input
• Thermal limiting, ripple rejection is 75dB typ at (VIN = 7V(avg), VRIPPLE = 0.5VP-P)
• Output voltage noise is 100µVRMS typical at (COUT = 10µF, ILOAD = 200mA, BW = 10Hz to 100KHz)
• Operating temperature range from -40°C to 125°C
• Package style is 12-lead plastic DFN
