LT3014BIS5#TRMPBF

LT3014BIS5#TRMPBF is a high-voltage, micropower low dropout linear regulator. This device is capable of supplying 20mA of output current with a dropout voltage of 350mV. Designed for use in battery-powered or high-voltage systems, the low quiescent current (7µA operating) makes the LT3014B an ideal choice. Quiescent current is also well controlled in dropout. Other features of the LT3014B include the ability to operate with very small output capacitors. The regulator is stable with only 0.47µF on the output, while most older devices require between 10µF and 100µF for stability. Small ceramic capacitors can be used without the necessary addition of ESR, as is common with other regulators. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting, and reverse current protection. Applications include low-current high-voltage regulators, regulators for battery-powered systems, telecom applications, and automotive applications.

• Wide input voltage range from 3V to 80V, no protection diodes needed
• Stable with 0.47µF output capacitor, thermal limiting
• Reverse-battery protection, no reverse current flow from output
• Stable with aluminium, tantalum or ceramic capacitors
• Dropout voltage is 120mV typical at (ILOAD = 100µA, TJ = 25°C)
• GND pin current is 7µA typical at (ILOAD = 0mA, TJ = 25°C)
• Output voltage noise is 115µVRMS typical at (COUT = 0.47µF, ILOAD = 20mA, BW = 10Hz to 100KHz)
• Ripple rejection is 70dB typical at (VIN = 7V (avg), VRIPPLE = 0.5VP-P, fRIPPLE = 120Hz)
• Reverse output current is 2µA typical at (VOUT = 1.22V, VIN < 1.22V, TJ = 25°C)
• Operating junction temperature range from -40°C to 125°C, 5-lead plastic SOT-23 package
