1.5A LDO regulators are in ‘smallest’ package

Low dropout (LDO) regulators in the TCR15AG series are offered in the industry’s smallest WCSP6F package, claims Toshiba Electronics Europe. The package measures 1.2 x 0.8 x 0.3mm.

There are 47 voltage options in the TCR15AG series and the regulators are suitable for any mobile or modular application that requires a small, thin LDO device with high current handling capability.

Despite its size, the TCR15AG series drives high current levels of 1.5A, making it suitable for power supply circuits in RF applications such as Wi-Fi chipsets or internet of things (IoT) and wireless modules. The TCR15AG series can also control power supply in applications requiring a high current, including notebook PCs, digital camcorders, storage devices and set-top boxes.

The TCR15AG series delivers the industry’s best-in-class ripple rejection ratio (95dB) and fastest load transient response, claims Toshiba, significantly reducing the ripple and noise from a power management IC (PMIC) or a DC/DC converter. This ripple and noise is often a limiting factor in the power supply for cameras and RF circuits. The TCR15AG series LDOs help to minimise output voltage fluctuations that occur in response to sharp changes in current during mode transitions in cameras and RF circuits.

Low voltage dropout is secured by the use of an external bias voltage (VBIAS), which helps to improve system power efficiency and contributes to a longer time between charges for mobile product batteries.

The TCR15AG series enables support for a wide range of power supply applications as it has additional protection features, including over-current protection and thermal shutdown, and offers adjustable as well as fixed output voltage types. The fixed output voltage types are available from 0.65 to 3.6V, whilst the adjustable type can be set between 0.6 and 3.6V via external resistors.
