LP38692SD-ADJ

The LP38692SD-ADJ is a high performance low-dropout (LDO) linear regulator designed for low-noise, high power-supply rejection ratio (PSRR) performance in space-constrained applications. It features an adjustable output voltage from 2.0V to 8.0V with a maximum output current of 1A and an ultra-low 0.4∆V dropout voltage. Designed for safety critical and harsh operating environment applications, it provides a wide temperature operating range of -40°C to +125°C.

The LM38692SD-ADJ\'s architecture and operation are optimized to produce maximum PSRR. Its NSCC (Non-Saturated Current Control) architecture uses a unique precision-trimmed voltage reference to generate a low output error voltage beyond the droop voltage and ensures PSRR performance over line and load extremes. NSCC also controls output current similar to a power-limited control scheme, leading to low output impedance and high load transient response.

The LP38692SD-ADJ employs a PMOS pass device, allowing higher dropout voltage, faster transient response and higher PSRR compared to conventional LDO regulators. A low quiescent current mode makes it ideal for low power applications.

The LP38692SD-ADJ offers numerous features to satisfy the requirements of various applications. It provides an adjustable output voltage from 2.0V to 8.0V, a maximum output current of 1A and an ultra-low 0.4∆V dropout voltage. The ENABLE pin is designed to reduce the total operating current to 1uA or less when the LP38692SD-ADJ is disabled, making it suitable for power-sensitive applications. Other features include low output noise operation and reliability, reverse current protection, thermal foldback protection, fixed start-up delay time and programmable soft-start.

The combination of wide input voltage range, high output voltage accuracy, low dropout voltage and high PSRR makes the LP38692SD-ADJ ideal for a wide range of applications. It is particularly suitable for powering notebook PCs, tablets, media centers and applications that require low operating current and noise-free, high efficiencies.

In summary, the LP38692SD-ADJ is a high-performance, low-dropout linear regulator designed for low-noise, high-power-supply rejection ratio (PSRR) performance in space-constrained applications. It features an adjustable output voltage from 2.0V to 8.0V with a maximum output current of 1A and an ultra-low 0.4∆V dropout voltage. Designed for safety critical and harsh operating environment applications, it provides a wide temperature operating range of -40°C to +125°C. It is suitable for powering notebook PCs, tablets, media centers and applications that require low operating current and noise-free, high efficiencies.
