CROSS-REFERENCE ALTERNATIVE
COS29302 is a Chinese-manufactured Low-Dropout Linear Regulator from COSINE (科山芯创) that cross-references to MIC29302WU (MICROCHIP), and also to LM29302.
It is a TO-263-5 device positioned as a domestic-supply option against the imported: shorter lead times, no allocation risk and a stable price for volume production. Because the parts are not pin-identical in every case, the engineering checklist below lists what to verify before you commit.

COS29302 — Low-Dropout Linear Regulator, alternative to MIC29302WU
COS29302 is supplied by Shenzhen Jingteng Electronics (JTDZ Tech) as a domestically sourced option for MIC29302WU (MICROCHIP), LM29302 (TI). Imported parts in this class are frequently subject to allocation, long lead times and steep price swings. A Chinese-manufactured equivalent removes that exposure: the parts are production-validated in industrial, consumer and automotive designs and ship from stock on a short lead time.
Cross-reference chart — which imported parts does COS29302 replace?
Every imported part number that COS29302 is published as a cross-reference alternative to, per the COSINE (科山芯创) 2025 selection table:
| imported part number | brand | Replaced by (this part) |
|---|---|---|
| MIC29302WU | MICROCHIP | COS29302 |
| LM29302 | TI | COS29302 |
Cross-reference means functional equivalence in the same application role. It is not a blanket claim of pin-for-pin identity — confirm package, pinout and the parameters listed below before you release a design change.

What to verify before substituting COS29302
These are the parameters that decide whether a cross-reference works in practice. Run through the list against the datasheet before releasing a change:
- Dropout voltage at your maximum load current, at the temperature you care about
- Maximum output current and the thermal path — TO-263 and SOT-23 dissipate very differently
- Quiescent and ground current, which decides standby life in battery designs
- Output capacitor requirement and stability: many older LDOs need ESR in a specific window and go unstable with modern ceramic capacitors
- Transient response and the resulting voltage droop on load steps
- Fixed vs adjustable output and the reference voltage if adjustable
- Protection features: current limit, thermal shutdown, reverse-battery protection
- Package and pinout
Typical applications
- Post-regulation after a switching supply
- Analogue and RF rail clean-up
- MCU and sensor power rails
- Battery-powered and portable systems
- Industrial control and instrumentation rails
- Automotive body electronics
