TL750L05CKC

The TL750L05CKC is a three-terminal low-dropout (LDO) linear voltage regulator with an adjustable output voltage from 1.5V to 15V. It is mainly used in applications where low noise, high accuracy, and low cost requirements are present. The device is designed to achieve the perfect balance between power efficiency, output accuracy, and superior temperature performance. It is suitable for low and medium power applications, including portable electronic devices, powering memory and processors for industrial applications, computing and communication systems, fanless PCs and microcontrollers.

The TL750L05CKC has a maximum quiescent current of 30 µA, and its load regulation is typically 2.5 mV/mA at 5V. It has excellent line and load transient response characteristics, a maximum error of 1% at 24V, temperature coefficient of 20 ppm/°C, and a maximum power dissipation at 25°C of 0.7W. The device also offers very high ripple rejection performance of 90 dB at 1 kHz and a low dropout voltage of 0.2V (typical) at 1mA.

The working principle of the TL750L05CKC is based on a two stage voltage regulator configuration. The first stage is the control stage, where an error amplifier compares the output voltage with the reference voltage. The output of the error amplifier is used to control the current reference to the pass transistor. The pass transistor (also known as the series mode pass transistor) is the second stage in this regulator configuration, and its role is to pass the current from the input to the output of the device, thereby regulating the output voltage. The constant current reference from the control stage is used to control the pass transistor in order to maintain the desired output voltage.

The TL750L05CKC offers excellent protection features such as over-temperature shutdown, under-voltage lockout and an overload protection circuit. The device is available in two packages, the TSOP-6 and the SOT-25. It can be used with a variety of external devices to implement various application functions, such as low dropout regulators, active filters and voltage followers.

In conclusion, the TL750L05CKC is a low-dropout linear voltage regulator that is suitable for applications requiring low noise, high accuracy, and low cost. Its low quiescent current, excellent line and load transient response characteristics, and high ripple rejection make it an ideal choice for powering memory and processors for industrial applications, computing and communication systems, fanless PCs and microcontrollers. It is available in two packages and offers a variety of protection features to ensure maximum performance and reliability.
