Toshiba Electronics Europe has underlined its strength in power management by announcing the introduction of its new TCR5RG series. These low drop-out (LDO) voltage regulators cover an output voltage range of 0.9 V to 5.0 V, thereby giving them scope to be employed in a wide variety of potential applications. They have a 100 dB ripple rejection ratio (when operating at a 1 kHz frequency). This has been achieved through the combination of a wide-gap internal circuit topology, an integrated high-speed operational amplifier supporting low noise operation, plus low-pass filtering.
The expansive LDO series comprises a total of 45 different devices, all of which are housed the ultra small plastic mold package WCSP4F (0.645 mm × 0.645 mm (typ.); t 0.33 mm (max)) that take up only minimal PCB space. They support a maximum output current of 500 mA and have a 5 μV (typical) output voltage noise, with a ±1.5% output voltage accuracy at voltages between 1.8 V and 2.8 V (going to ±1.8% for voltages above 2.8 V) and a chip temperature range of –40 °C to +85 °C.
Thanks to their mix of elevated performance parameters and a compact form factor, the TCR5RG series devices are optimised for implementation within space-constrained, high density electronic systems. Key uses include sensor-based system, IoT-chipset, RF systems, wearable technology and portable audio equipment, as well as healthcare monitoring units.
