M Di ain sc te on na tin nc ue e/ d The AN78LxxM series are 3-pin, fixed positive output type monolithic voltage regulators. Stabilized fixed output voltage is obtained from unstable DC input voltage without using any external components. 12 types of fixed output voltage are available; 4 V, 5 V, 6 V, 7 V, 8 V, 9 V, 10 V, 12 V, 15 V, 18 V, 20 V and 24 V. They can be used widely in power circuits with current capacity of up to 100 mA. The AN78L12M is the 12 V output voltage type in these series. y 3-pin positive output voltage regulator (100 mA type) Package y 3-pin plastic single inline package with heat sink (SIP type) Type Pl ea Ma int en an ce /D isc on tin ue y Silicon monolithic bipolar IC SFF00111BEB 3 int Ma an en 3 CIN CIN : 0.33 μF COUT : 0.1 μF R1 : 4 kΩ R2 : 8 kΩ R2 + – 2 Common Pl ea d pla inc ne lud se pla m d m es v ne ain ain foll htt isit d te t o p:/ fo /w llo dis disc nan enan wing ww wi co on ce c fo .se ng ntin tin ty e ty ur mi UR ue ued pe pe Pro co L a d t ty du n.p bo yp pe ct life an ut e d as lat cy on es cle ic. t in sta co fo ge .jp rm . /en at i o / n. ue on tin isc ce /D Input Voltage Reference Starter M Di ain sc te on na tin nc ue e/ d AN78L12M Block Diagram Current Source Pass Tr Current Limiter Error Amp.

(2) The technical information described in this book is intended only to show the main characteristics and application circuit examples of the products. No license is granted in and to any intellectual property right or other right owned by Panasonic Corporation or any other company. Therefore, no responsibility is assumed by our company as to the infringement upon any such right owned by any other company which may arise as a result of the use of technical information described in this book. M Di ain sc te on na tin nc ue e/ d (3) The products described in this book are intended to be used for standard applications or general electronic equipment (such as office equipment, communications equipment, measuring instruments and household appliances). Consult our sales staff in advance for information on the following applications: – Special applications (such as for airplanes, aerospace, automobiles, traffic control equipment, combustion equipment, life support systems and safety devices) in which exceptional quality and reliability are required, or if the failure or malfunction of the products may directly jeopardize life or harm the human body. – Any applications other than the standard applications intended. d pla inc ne lud se pla m d m es ne ain ain foll htt visit d d te te ow p:/ fo d /w llo is isc nan nan ing ww wi co on ce c fo .se ng ntin tin ty e ty ur mi UR ue ued pe pe Pro co L a d t ty du n.p bo yp pe ct life an ut e d as lat cy on es cle ic. t in sta co fo ge .jp rm . /en at i / on . (4) The products and product specifications described in this book are subject to change without notice for modification and/or improvement. At the final stage of your design, purchasing, or use of the products, therefore, ask for the most up-to-date Product Standards in advance to make sure that the latest specifications satisfy your requirements. (5) When designing your equipment, comply with the range of absolute maximum rating and the guaranteed operating conditions (operating power supply voltage and operating environment etc.). Especially, please be careful not to exceed the range of absolute maximum rating on the transient state, such as power-on, power-off and mode-switching. Otherwise, we will not be liable for any defect which may arise later in your equipment. Even when the products are used within the guaranteed values, take into the consideration of incidence of break down and failure mode, possible to occur to semiconductor products. Measures on the systems such as redundant design, arresting the spread of fire or preventing glitch are recommended in order to prevent physical injury, fire, social damages, for example, by using the products. (6) Comply with the instructions for use in order to prevent breakdown and characteristics change due to external factors (ESD, EOS, thermal stress and mechanical stress) at the time of handling, mounting or at customer's process. When using products for which damp-proof packing is required, satisfy the conditions, such as shelf life and the elapsed time since first opening the packages.
