STMicroelectronics (STMicroelectronics, ST) unveiled a tiny size LDBL20 200 ma, low pressure drop linear regulators (they). New products with 0.47 mm x 0.47 mm x 0.2 mm wafer level packaging, can be used as a wearable device, portable device and multi-function networking smart card with flexible device is an ideal choice.

LDBL20 STSTAMP no bumps breaks through traditional flip chip packaging welded convex point diameter on the I/O area high minimum size limit, make the package size of compact degree reached unprecedented levels. LDBL20 stmicroelectronics compact low pressure drop is linear regulators the new members of the family of products, including from 2 mm x 2 mm DFN to 300 ma output current of 0.69 mm x 0.69 mm wafer level packaging of various products.

In addition to the size advantage, LDBL20 performance is very excellent. 200 ma output current to make its performance comparable to other factory product size bigger. The output voltage range from 1.5 V to 5.5 V, the typical pressure drop 200 mv. 100 hz 100 KHZ and power supply rejection ratio (PSRR) 80 db and 50 db, respectively, to simplify the design of broadband filter circuit for the battery the low power circuit of the power supply device to provide stable voltage. No-load static current 20 mu, 100 mu A full static current, 0.3 mu A standby, helps to maximize efficiency under various operation status.

This series of products to ask according to demand to provide 0.8 V to 0.8 V output voltage, the increment of 50 mv. LDBL20 built-in functions are very abundant, including internal logic control electronic shut off, soft start, if necessary, can also support the active output voltage discharge.

LDBL20 evaluation board STEVAL - ISB034V1 and launched new products and help LDBL20 design to all kinds of products, including the fitness of the prison and the blood pressure monitor, blood sugar, hearing AIDS, wear sensor, wisdom, earphone, portable audio device, intelligence, wisdom, watches and smart card socket.

LDBL20 is now mass production.
