Ordering number:ENN2300A Monolithic Linear IC LA5667 Multifunction Multiple Voltage Regulator Overview • Especially suited for use in micorcomputer-controlled tuners, receivers, preamplifiers and the like. Features • Two independent regulators contained in a single chip (13.0V/350mA, 5.6V/100mA). • Reset circuit which delivers the reset signal on the positive transition, negative transition of the 5.6V output. • Muting circuit which detects the 13.0V input and reset output to deliver the mutin.

Ordering number:ENN2300A Monolithic Linear IC LA5667 Multifunction Multiple Voltage Regulator Overview • Especially suited for use in micorcomputer-controlled tuners, receivers, preamplifiers and the like. Features • Two independent regulators contained in a single chip (13.0V/350mA, 5.6V/100mA). • Reset circuit which delivers the reset signal on the positive transition, negative transition of the 5.6V output. • Muting circuit which detects the 13.0V input and reset output to deliver the muting signal (We have the LA5665 whose detection function for reset, muting is provided on the output voltage side).

To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer's products or equipment. SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all semiconductor products fail with some probability. It is possible that these probabilistic failures could give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire, or that could cause damage to other property. When designing equipment, adopt safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective circuits and error prevention circuits for safe design, redundant design, and structural design. In the event that any or all SANYO products(including technical data,services) described or contained herein are controlled under.
