LT3007 Series
3µA IQ, 20mA, 45V
Low Dropout Fault Tolerant
Linear Regulators
DESCRIPTION
The LT®3007 series are micropower, low dropout voltage
(LDO) linear regulators. The devices supply 20mA output
current with a dropout voltage of 300mV. No-load quies-
cent 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 LT3007 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 reverse-
current protection.
The LT3007 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 LT3007 is available in the thermally
enhanced 8-lead TSOT-23 package.
