PMIC, or Power Management ICs, are devices that are specially designed to control the power distribution of a system in order to optimize efficiency, increase battery life, and improve performance. Voltage regulators, a type of PMIC, are critical components in any electronic system. They provide the ability to accurately adjust the output voltage and current levels to exactly meet the system design requirements.
Simplifying power management tasks and reducing overall system cost and complexity are challenges that many end users face when selecting voltage regulators for their design. For these situations, the L7915CD2T-TR fixed positive voltage regulators from Diodes Incorporated are cost-effective solutions that provide high performance and reliability.

The L7915CD2T-TR is a four-pin SOT-89 fixed positive voltage regulator that is capable of providing output voltages of 1.5V, 1.8V, 2.5V, 3.3V, 5V, and 6V. It is ideal for a variety of regulated DC power applications including computers and peripherals, communication systems, and industrial, automotive, and consumer electronics. The device is characterized by an ultra-low quiescent current of only 2.2µA (typical, at no load), and an improved line regulation of 0.25% (max). Another major benefit of the L7915CD2T-TR is its high output voltage accuracy over temperature, which is 2.0% (max). With a switching frequency of 200kHz (typical), the device can operate at up to 1.5A load (including high capacitive loads) with excellent line and load transient response.

The L7915CD2T-TR is designed with a very basic internal architecture which consists of an error amplifier and a series pass element connected in a voltage divider configuration. The output voltage is set by an external voltage divider and an internal reference voltage, typically 1.247V. The output voltage is controlled and stabilized by an external error amplifier that is connected in a negative feedback configuration. The output voltage is compared to the internal reference voltage and an error voltage is derived from the difference between the two. The error voltage is then used to control the gate voltage of the series pass element. The output voltage can be adjusted by changing the voltage divider values.

In conclusion, the L7915CD2T-TR fixed positive voltage regulators from Diodes Incorporated address the challenges set forth by end users when selecting a voltage regulator for their designs. With its wide selection of adjustable voltage outputs, low quiescent current and high level of accuracy, the L7915CD2T-TR is an ideal choice for a wide range of regulated DC power applications. Furthermore, the device’s extremely simple circuit topology makes it an ideal choice for cost-effective power management solutions.
