What are the key features of MCP1799T-5002H/DB?
- Fixed 5.0 V output with input range 6.2 V to 45 V — ideal for high-voltage bus regulation
- Ultra-low dropout voltage as low as 0.3 V nominal, up to 1.1 V max at full load
- SOT-223 package delivers efficient thermal dissipation for up to 150 mA output current
- Absolute maximum input voltage of 66 V provides robust overvoltage protection margin
What is MCP1799T-5002H/DB used for?
The MCP1799T-5002H/DB is well-suited for industrial equipment requiring stable 5.0 V logic rails derived from high-voltage power buses ranging up to 45 V. It also serves automotive pre-regulation stages, motor drive control boards, and any design where a compact, high-input-voltage LDO with low quiescent current is needed. Its wide input range makes it a reliable choice for converting 24 V or 48 V industrial rails down to a clean 5.0 V supply.

Frequently Asked Questions
What is the maximum input voltage the MCP1799T-5002H/DB can handle continuously?
The MCP1799T-5002H/DB accepts a continuous input voltage up to 45 V, with an absolute maximum rating of 66 V. This wide input range makes it suitable for industrial and automotive applications running from 24 V or 48 V power buses while delivering a regulated 5.0 V output at up to 150 mA.
How does the MCP1799T-5002H/DB perform in a 24 V industrial panel that must power 5 V logic circuits?
With a 24 V input well within its 6.2 V to 45 V operating range, the MCP1799T-5002H/DB maintains a regulated 5.0 V output at up to 150 mA with a dropout voltage as low as 0.3 V nominal. The SOT-223 package provides adequate thermal dissipation for the 2.85 W power dissipation in typical panel installations.
When should a designer choose MCP1799T-5002H/DB over a switching regulator for high-voltage to 5 V conversion?
The MCP1799T-5002H/DB is preferred when low noise, simplicity, and minimal component count outweigh efficiency concerns. It requires no inductor and produces no switching noise, which is critical in noise-sensitive analog or sensor circuits. For loads under 150 mA and input voltages up to 45 V, the design simplicity and small 3-pin SOT-223 footprint often justify the linear regulation efficiency trade-off.
What temperature range does the MCP1799T-5002H/DB support for automotive or outdoor industrial use?
The MCP1799T-5002H/DB is rated for an operating temperature range of -40°C to +125°C, making it suitable for automotive under-hood environments and industrial outdoor enclosures where temperatures vary widely across seasons and operating conditions.
