Dolphin Integration enrich their Reusable Power Kit Library DELTA with Linear Regulators optimized for noise sensitive applications

Grenoble, France – February 24, 2014 -- Dolphin Integration, provider of innovative solutions for low power-consumption have released a complete family of Linear Regulators for embedding any traditional discrete LDO. They now effectively target the protection of noise sensitive blocks such as Audio converters, PLL and RF blocks with low noise Linear Regulators (nLR).

Any such nLR has been optimized for:

• A power supply rejection template extended over the whole relevant spectrum, starring a PSRR of -65 dB at 20 kHz
• A small footprint, of only 0.12 mm² for the nLR-VAIPO!
• Minimizing the overall system power, through the support of the 3 modes of operation: normal, shutdown and bypass

The large variety of permitted ranges of power supply enable connections to the main power sources requested on the market.

To ease integration in complex systems-on-chip, these nLR are delivered with new views as behavioral models for streamlined checks. Such views enable to build a safely optimized Power Management Network (PMNet) by securing mode transitions, as well as resilience to noise propagated throughout the PMNet.

Dolphin Integration’s set of ultra low noise Linear Regulators involves 2 structures:

The nLR-VAIPO structure

• Parametrized to support from 100 mA, up to 500 mA maximum load current
• With a Power OK (POK) circuit indicating the establishment of the regulator output
• A large input supply range from 1.62 V to 3.63 V, to support direct connection to double alkaline, NIMH, lithium coin cells, and system power supply
• Delivering 2 output voltages (1.2 V or 2.5 V) to provide a range of solutions for supplying RF, PLL and Audio conversion blocks

Both regulator structures are available for the 65/55 nm technological processes at TSMC and SMIC.

The Linear Regulator family includes more regulator components to optimize the PMNet for other criteria, esp. low BoM (thanks to capless solutions) or low power (thanks to solutions with ultra low quiescent current).
