LM323 datasheet

 

Description

The LM123 is a three-terminal positive regulator with a preset 5V output and a load driving capability of 3 amps. New circuit design and processing techniques are used to provide the high output current without sacrificing the regulation characteristics of lower current devices.

The LM323A offers improved precision over the standard LM323-N. Parameters with tightened specifications include output voltage tolerance, line regulation, and load regulation.

Features

1. Ensured 1% Initial Accuracy (A Version)
2. 3 Amp Output Current
3. Internal Current and Thermal Limiting
4. 0.01Ω Typical Output Impedance
5. 7.5V Minimum Input Voltage
6. 30W Power Dissipation

Part Number: B4252CK5-4.5

Function: 4.5V, 250mA, Low Dropout Voltage Regulator

Package: SOT-25 Type

Manufacturer: Bay Linear

Pinouts:

B4252CK5-4.5 datasheet

 

Description

The B4252 series are a group of positive output voltage, five-pin regulators, which provide a high current even when the input/output voltage differential is small. Low power consumption and high accuracy is achieved though CMOS and programmable fuse technologies. Output voltage : 2.0V to 6.0V in 0.1V increments. The B4252 consists of a high-precision voltage reference, an error correction circuit, and a current limited output driver. Key features include a Shutdown Pin that reduces supply current to 0.5µA max and a 470pF Bypass input to ground reduces noise present on the internal reference, which in turn significantly reduce output noise. If output noise is not concern, this input maybe left unconnected. Larger capacitor values cap be used, but results in longer time period to rated output voltage when power initially applied.

Features

1. Maximum Output Current : 250 mA.
2. Highly Accurate Output Voltage +/- 1.4%
3. Only 19μA Power Consumption MAX
4. Shutdown Supply Current 1μA
5. Ground Current of Less than 5μA

Applications

1. Battery Powered Equipment
2. Notebook PC, Palmtops, PDA
3. Portable Cameras and Video Recorders
4. Reference Voltage Sources
5. Cellular / GSM / PCS Phones
