LT3020 - 100mA, Low Voltage, Very Low Dropout Linear Regulators
LT3020 - 100mA, Low Voltage, Very Low Dropout Linear Regulators - Linear Technology（凌力尔特）
The LT3020 is a very low dropout voltage (VLDO?) linear regulator that operates from input supplies down to 0.9V. This device supplies 100mA of output current with a typical dropout voltage of 150mV. The LT3020 is ideal for low input voltage to low output voltage applications, providing comparable electrical efficiency to that of a switching regulator.
The LT3020 regulator optimizes stability and transient response with low ESR, ceramic output capacitors as small as 2.2μF. Other LT3020 features include 0% line regulation and 0.2% typical load regulation. In shutdown, quiescent current typically drops to 3μA.
Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting with hysteresis, and reverse-current protection. The LT3020 is available as an adjustable output device with an output range down to the 200mV reference. Three fixed output voltages, 1.2V, 1.5V and 1.8V, are also available.
The LT3020 regulator is available in the low profile (0.75mm) 8-lead (3mm × 3mm) DFN package with exposed pad and the 8-lead MSOP package.
