Current and voltage requirements vary considerably in different applications. This requires custom linear voltage regulators (LDOs) to meet these ever-growing demands, thereby providing precise control, low noise, and low ripple currents. AZ78L05ZTR-E1 is a low dropout (LDO) regulator capable of delivering up to 1A output current with a very low quiescent current. This device is suitable for a wide range of features, including applications within telecom, computing and networking, and electronic office, such as industrial equipment and portable electronic systems.

The AZ78L05ZTR-E1 is a three-terminal regulator which provides an adjustable output voltage of 1.24V to 16V. It offers a low dropout voltage of 1V and a typical quiescent current of 10µA. It ensures low noise and wide temperature operating range of -55°C to +125°C. The AZ78L05ZTR-E1 is designed to offer excellent line and load transient specifications, as well as excellent PSRR performance to meet strict requirements of low-voltage system applications. The typical maximum minimum voltage range is 1.2V to 20V, and the maximum output current is 1A.

The AZ78L05ZTR-E1 uses a series-pass design which includes a divider network and a precision-adjustable reference. This device uses an external protection diode to protect the output from excessive voltages. In order to balance a tight output voltage over temperature, the accuracy of the reference is important. The AZ78L05ZTR-E1 uses a low-noise voltage reference. The reference voltage of the device is set by connecting an external voltage divider network to the reference pin.

The AZ78L05ZTR-E1 has a singleenable input that shuts down the device when pulled low. This reduces quiescent current to a typical value of 0.45uA at 10V. The device also has a new "low dropout-low ESR" design which enables the design of less noisy and more efficient solutions. The device has a low-noise pin which allows the user to optimize the device performance while reducing the noise. Additionally, the device has an output disconnect feature which allows the output voltage to be disconnected from its load.

The AZ78L05ZTR-E1 offers excellent line and load transient characteristics. It has a low output impedance and typically provides a reduced output voltage ripple. The internal design features an adjustable voltage reference, low input and output impedance, and an internal ESR. This ensures excellent regulation over line, load, and temperature variation. The device also offers a wide range of protection features including high-side current limit and reverse current protection, over-temperature protection, and current overload protection. The AZ78L05ZTR-E1 is available in a wide range of packages such as SOT, SOIC, and DIP.
