LM2936MPX-3.3/NOPB 詳細描述
Product Overview
LM2936MPX-3.3/NOPB from Texas Instruments is a fixed positive-output linear voltage regulator intended for low-current regulation tasks. The device provides a single 3.3 V output at up to 50 mA and has a maximum input voltage of 40 V. It uses a surface-mount SOT-223-4 package, also identified as TO-261-4 or TO-261AA. The regulator combines a 0.4 V maximum dropout at 50 mA, 15 µA quiescent current, and protection against over-temperature, reverse polarity, and short-circuit conditions, with an operating junction temperature range of -40°C to 125°C.
Key Features
- Fixed 3.3 V positive output from a single regulator channel.
- 50 mA maximum output current with 0.4 V dropout at 50 mA.
- Maximum input voltage of 40 V.
- 15 µA quiescent current and 2.5 mA maximum supply current.
- 60 dB power supply rejection ratio at 120 Hz.
- Over-temperature, reverse-polarity, and short-circuit protection.
- Surface-mount SOT-223-4 package, TO-261-4 / TO-261AA.
- Operating junction temperature range from -40°C to 125°C.
Applications
- Generating a fixed 3.3 V rail for low-current circuitry from a higher DC input.
- Providing a stable low-current supply in compact surface-mount designs where board space is limited.
- Supporting circuits where a 15 µA quiescent current is relevant to low standby current.
- Regulating higher input voltages, up to 40 V, with a 0.4 V dropout at 50 mA.
- Implementing regulation where over-temperature, reverse-polarity, and short-circuit protection features are required.
Design & Procurement Notes
When selecting this regulator, verify that the load current remains within 50 mA and that the input voltage does not exceed 40 V. The fixed 3.3 V output means the input must provide sufficient headroom for the 0.4 V dropout at the 50 mA current point. The SOT-223-4 surface-mount package and junction temperature limit of 125°C should be considered for board layout and thermal management. The 15 µA quiescent current and 2.5 mA maximum supply current are relevant for low-current designs, while the protection features support regulated operation under fault conditions.
