| FFF Compatibility | The SOT-23A-3 package package and pinout assignments (Pin 1: GND, Pin 2: VOUT, Pin 3: VIN) are a direct drop-in match for the HT7133 SOT-23 package pinout.Standard SOT-23 package outline with identical mounting footprints.Max input voltage is limited to 16V, whereas the original HT7133 supports up to 24V input. If the application supply voltage is below 16V, it is fully functional. | Uses SOT-23A-3 (CB suffix) layout which assigns GND to pin 1, VOUT to pin 2, and VIN to pin 3, perfectly matching the HT7133 SOT-23 layout.Standard SOT-23-3 physical body profile.Input voltage is limited to 13.2V maximum, which is lower than the HT7133's 24V ceiling. | ||
 AI Summary | HT7133 by GOODWORK: Linear Voltage Regulator IC Positive Fixed 1 Output 30mA SOT-23. | A highly reliable, low-quiescent-current 3.3V linear regulator from Microchip. It offers a direct drop-in layout match on the SOT-23 package with significantly higher output current, though its maximum input voltage is reduced to 16V.
| An excellent low-power LDO option with a pin-compatible SOT-23 footprint. It delivers 250mA of output current with 2 µA of Iq, but is limited to a maximum input voltage of 13.2V.
