Description

The AX6603 is a 300mA, low quiescent, high PSRR, low noise and low dropout linear regulator. The Device includes pass element, error amplifier, band-gap, current-limit and thermal shutdown circuitry. The characteristics of low dropout voltage and less quiescent current make it good for some critical current application, for example, some battery powered devices. The typical quiescent current is approximately 90µA. In the shutdown mode, the maximum supply current is less than 1uA. Due to internal flexible design, result in extensively fixed output voltage versions form 1.0V to 5V per 0.1V steps. Built-in current-limit, Short current protection and thermal-shutdown functions prevent any fault condition from IC damage.

Features

1. Input voltage range : 2.6V~6.0V

2. Dropout voltage is 200mV at 150mA output current

3. Guaranteed 300mA output current

4. Low quiescent current is 90µA  (typ.)

5. Maximum supply current in shutdown mode <1uA

6. Fixed Output voltage is form 1.0V to 5V by 0.1V steps.

7. Fast transient response

8. Current limit and thermal shutdown protection

9. Short circuit current fold-back

10. Available in the TSOT-23-5L, SC82-4L and TDFN-6L Packages

Part Number: LM2594

Function: 0.5A, Step-Down Switching Regulator

Package: SOIC-8, PDIP-8 Pin type

Manufacturer: ON Semiconductor

Description

The LM2594 regulator is monolithic integrated circuit ideally suited for easy and convenient design of a step−down switching regulator (buck converter).

The regulator is monolithic integrated circuit ideally suited for easy and convenient design of a step−down switching regulator(buck converter). It is capable of driving a 0.5 A load with excellent line and load regulation. This device is available in adjustable output version. It is internally compensated to minimize the number of external components to simplify the power supply design.

Since LM2594 converter is a switch−mode power supply, its efficiency is significantly higher in comparison with popular three−terminal linear regulators, especially with higher input voltages.

The device operates at a switching frequency of 150 kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Available in a standard 8−Lead PDIP and 8−Lead Surface Mount packages.

Features

• Adjustable Output Voltage Range 1.23 V ~ 37 V
• Guaranteed 0.5 A Output Load Current
• Wide Input Voltage Range up to 40 V
• 150 kHz Fixed Frequency Internal Oscillator
• TTL Shutdown Capability
• Low Power Standby Mode, typ 50 A
• Thermal Shutdown and Current Limit Protection
• Internal Loop Compensation
• Moisture Sensitivity Level (MSL) Equals 1
• These are Pb−Free Devices
