3.3V SOT-23-5 LDO candidate, but lower current and unverified pinout need review.
ME6211C33M5G-N is a 3.3V 500mA SOT-23-5 LDO. Alternatives need pinout, load, dropout, and capacitor checks.
current/dropout/PSRR may change
same package, pinout missing
analog LDO
lifecycle data limited
No pin-compatible replacement is verified from the provided evidence.
Review GR6220B331MR-G first if the load is within 300mA.
Pinout is not verified and some candidates reduce current or analog performance.

| Feature / factor | ME6211C33M5G-N | GR6220B331MR-G | GR6219B332MR | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SOT-23-5 | SOT-23-5 | SOT-23-5 | SOT-23-5 — same package name; GR6219B332MR: same package name | |
| Pinout | 5 pins | 5 pins | 5 pins | 5 pins — functions missing; GR6219B332MR: functions missing | |
| Voltage | Vin 2-6V | Vin max 7V | 3.3V fixed | Vin max 7V / 3.3V fixed — min Vin missing; GR6219B332MR: same output | |
| Current | 500mA | 300mA | 300/500mA | 300mA / 300/500mA — load derating; GR6219B332MR: ES conflict | |
| Application | 70dB, 120mV | - | 40dB, 280mV | 40dB, 280mV — noise/headroom risk |
GR6220B331MR-G is the closest kept candidate, but only for loads up to 300mA after pinout review.
