Voltage Regulators AN78xxR/AN78MxxR Series 4-pin positive output voltage regulator with reset pin (1 A/500 mA type) ■ Overview Unit: mm The AN78xxR series and the AN78MxxR series are the fixed positive output type monolithic voltage regulators with reset pin. Stabilized fixed output voltage is obtained from unstable DC input voltage without using any external components. Three types of output voltage, 5V, 9V and 12V, are available for the AN78xxR series, and four types, 5V, 8V, 9V and 12V, are available for the AN78MxxR series. They can be used in power circuits with current capacity of 1A/500mA. On/off of output voltage can be controlled by the reset pin. 9.6+0.5 –0.1 3–1.0 1.8 4.0 2.0 9.0 min. di p Pl lan nclu ea e se pla m d m des ne ain ain foll htt visit 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. ■ Features 12.5 max.

(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.
