Part Name(s) : LP2951-4.8 LP2951-4.8BM Micrel
Micrel
Description : 100MA LOW-DROPOUT VOLTAGE REGULATOR View

General Description
The LP2950 and LP2951 are micropower VOLTAGE REGULATORs with very LOW DROPOUT VOLTAGE (typically 40mV at light loads and 380mV at 100MA), and very LOW quiescent current (75µA typical). The quiescent current of the LP2950/LP2951 increases only slightly in DROPOUT, thus prolonging battery life. This feature, among others, makes the LP2950 and LP2951 ideally suited for use in battery-powered systems.
Available in a 3-Pin TO-92 package, the LP2950 is pin compatible with the older 5V REGULATORs. Additional system functions, such as programmable output VOLTAGE and logic controlled shutdown, are available in the 8-pin DIP and 8-pin SOIC versions of the LP2951.

Features
• High accuracy 5V, guaranteed 100 mA output
• Extremely LOW quiescent current
LOW-DROPOUT VOLTAGE
• Extremely tight load and line regulation
• Very LOW temperature coefficient
• Use as REGULATOR or reference
• Needs only 1µF for stability
• Current and thermal limiting

LP2951 Versions Only
• Error flag warns of output DROPOUT
• Logic-controlled electronic shutdown
• Output programmable from 1.24 to 29V

Applications
• Automotive Electronics
VOLTAGE Reference
• Avionics

 

Part Name(s) : LT3027 LT3027EDD LT3027IDD LT3027EMSE LT3027IMSE Linear
Linear Technology
Description : Dual 100MA, LOW DROPOUT, LOW Noise, Micropower REGULATOR with Independent Inputs View

DESCRIPTION
The LT ®3027 is a dual, micropower, LOW noise, LOW DROPOUT REGULATOR with independent inputs. With an external 0.01µF bypass capacitor, output noise is a LOW 20µVRMS over a 10Hz to 100kHz bandwidth. Designed for use in battery-powered systems, the LOW 25µA quiescent current per channel makes it an ideal choice. In shutdown, quiescent current drops to less than 0.1µA. Shutdown control is independent for each channel, alLOWing for flexibility in power management. The device is capable of operating over an input VOLTAGE from 1.8V to 20V, and can supply 100MA of output current from each channel with a DROPOUT VOLTAGE of 300mV. Quiescent current is well controlled in DROPOUT
