The LT3007ITS8 series are micropower, low dropout voltage (LDO) linear regulators. The devices supply 20mA output current with a dropout voltage of 300mV. No-load quiescent current is 3μA. Ground pin current remains at less than 5% of output current as load increases. In shutdown, quiescent current is less than 1μA.
The LT3007ITS8 regulators optimize stability and transient response with low ESR ceramic capacitors, requiring a minimum of only 2.2μF. The regulators do not require the addition of ESR as is common with other regulators. Internal protection circuitry includes current limiting, thermal limiting, reverse-battery protection and reversecurrent protection.
The LT3007ITS8 series are ideal for applications that require moderate output drive capability coupled with ultralow standby power consumption. The device is available in fixed output voltages of 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5V, and an adjustable version with an output voltage range of 0.6V to 44.5V. The LT3007ITS8 is available in the thermally enhanced 8-lead TSOT-23 package.
