What are the key features of TSR 1-24150?
- 1 A output current with input range of 4.6 V to 36 V DC, replacing LM78xx linears with up to 95% efficiency
- SIP-3 through-hole package is pin-compatible with LM7805/LM7812/LM78xx series for drop-in replacement
- Integrated switching regulator eliminates external heat sink required by linear alternatives, reducing thermal management cost
What is TSR 1-24150 used for?
The TSR 1-24150 is used in industrial control systems, embedded computing boards, and distributed power architectures as a drop-in replacement for LM78xx linear regulators. Operating from a wide 4.6 V to 36 V input, it suits 5 V, 12 V, or 24 V bus systems where minimizing power dissipation is critical. Its high efficiency of up to 95% makes it ideal for battery-powered equipment, IoT gateways, and field instruments where thermal headroom is limited.

Frequently Asked Questions
What input voltage range does the TSR 1-24150 support and what output voltage does it produce?
The TSR 1-24150 accepts an input voltage of 4.6 V to 36 V DC and delivers a regulated 1.5 V DC output at up to 1 A continuous load current. The wide input range makes it compatible with 5 V, 12 V, and 24 V power rails commonly found in industrial and embedded systems.
How does the TSR 1-24150 improve efficiency compared with an LM7815 linear regulator in a 24 V to 1.5 V conversion?
An LM7815 linear regulator dissipates (Vin - Vout) × Iout = (24 - 1.5) × 1 = 22.5 W as heat at full load, requiring a significant heat sink. The TSR 1-24150 switching regulator achieves up to 95% efficiency, dissipating less than 1.2 W and eliminating the heat sink, saving board space and reducing system temperature by more than 20°C.
Can the TSR 1-24150 be used as a direct drop-in replacement for an LM78xx regulator on an existing PCB?
Yes, the TSR 1-24150 uses a SIP-3 package with input, ground, and output pins that are pin-compatible with the standard LM78xx through-hole footprint. No PCB changes are required; simply replace the LM78xx component, and the switching regulator will provide the same 1.5 V regulated output at up to 1 A with significantly lower heat dissipation.
