TPS74901DRCR  

Linear & Switching Voltage Regulators

TPS74901DRCR is a low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments. It is designed to provide a stable and reliable voltage output for a wide range of applications.

Description:

The TPS74901DRCR is a compact, low-profile, and thermally-enhanced LDO regulator. It is available in a small DFN (Dual Flat No Lead) package, which makes it suitable for space-constrained applications. The device has a wide input voltage range of 1.8V to 5.5V and can deliver an output current of up to 1A.

Features:

1. Low dropout voltage: The TPS74901DRCR has a low dropout voltage of typically 300mV at maximum load, which ensures efficient power delivery even when the input voltage is close to the output voltage.
2. High PSRR: The device has a high power supply rejection ratio (PSRR) of typically 80dB at 1kHz, which minimizes the impact of input voltage fluctuations on the output voltage.
3. Low quiescent current: The LDO has a low quiescent current of typically 2.5µA, which helps to reduce power consumption in battery-powered applications.
4. Adjustable output voltage: The output voltage can be adjusted using an external resistor divider, allowing for customization to meet specific application requirements.
5. Thermal protection: The TPS74901DRCR features thermal shutdown and overcurrent protection to ensure safe operation and prevent damage in the event of an overload.

Applications:

The TPS74901DRCR is suitable for a wide range of applications that require a stable and reliable voltage source. Some common applications include:

1. Portable devices: Smartphones, tablets, and wearable devices often require a stable voltage source for their sensitive components. The TPS74901DRCR can provide this stability while also conserving power.
2. IoT devices: Internet of Things (IoT) devices often have limited power sources, making efficient power regulation essential. The TPS74901DRCR's low quiescent current and low dropout voltage make it an ideal choice for these applications.
3. Medical devices: Medical devices require stable and reliable power sources to ensure accurate operation. The TPS74901DRCR's high PSRR and thermal protection features make it suitable for these applications.
4. Industrial equipment: Industrial equipment often operates in harsh environments, making reliable power regulation crucial. The TPS74901DRCR's thermal and overcurrent protection features help ensure safe operation in these conditions.

In summary, the TPS74901DRCR is a versatile and efficient LDO voltage regulator that offers a stable and reliable voltage output for a variety of applications. Its low dropout voltage, high PSRR, low quiescent current, adjustable output voltage, and thermal protection features make it an ideal choice for portable devices, IoT devices, medical devices, and industrial equipment.
