TD1507 datasheet



The TD1507 is a series of easy to use fixed and adjustable step-down (buck) switch-mode voltage regulators. These devices are available in fixed output voltage of 5V, and an adjustable output version. Both versions are capable of driving a 3A load with excellent line and load regulation.

Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation, and a fixed-frequency oscillator.


1. 5V and adjustable output versions
2. Output adjustable from 1.23v to 43V
3. Fixed 150KHz frequency internal oscillator
4. Guaranteed 3A output load current
5. Input voltage range up to 45V
6. Low power standby mode, IQ typically 80 μA
7. TTL shutdown capability
8. Excellent line and load regulation
9. Requires only 4 external components


1. Simple High-efficiency step-down regulator
2. On-card switching regulators
3. Positive to negative converter
4. LCD monitor and LCD TV
