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).

Specifications of any and all SANYO products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer's products or equipment. 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.
